Our client, an early-stage AI company, is looking for an iOS Software Engineer to build the mobile experience for a next-generation proactive AI assistant.
This isn’t about adding AI features to an existing app. AI is the product.
You’ll own the iOS experience from the ground up, building an application where every interaction with the assistant feels fast, reliable, and intuitive.
If you care about building polished mobile products, solving complex UX challenges, and shipping software that millions of people could rely on, we’d love to hear from you.
RESPONSIBILITIES
Build and maintain production-quality iOS applications using Swift and SwiftUI
Integrate AI capabilities through backend APIs and ensure seamless user experiences
Design intuitive AI interaction patterns, including streaming responses, loading states, retries, and graceful fallbacks
Optimize application performance, memory usage, battery consumption, and responsiveness
Collaborate closely with backend and machine learning engineers on API design and AI behavior
Collect user signals and feedback to improve AI quality and product experience
Maintain high standards for App Store quality, stability, monitoring, and production reliability
Troubleshoot production issues, perform root cause analysis, and continuously improve application resilience
REQUIREMENTS
3+ years of professional iOS development experience with Swift
Strong experience building applications with SwiftUI
Experience integrating AI-powered features or intelligent backend services into mobile applications
Solid understanding of async/await, Swift concurrency, and background task management
Strong knowledge of iOS performance optimization, memory management, and battery efficiency
Experience shipping and maintaining production iOS applications
Comfortable designing software that handles latency, partial failures, and non-deterministic AI behavior
Strong product mindset with an eye for creating trustworthy AI user experiences
Experience with CoreML or lightweight on-device machine learning
Knowledge of SQL and NoSQL databases
NICE TO HAVE
Familiarity with TensorFlow Lite for on-device inference
Experience with feature flagging or remote configuration systems
Experience working in fast-moving startup environments
WHAT THEY OFFER
Cash and equity compensation
Remote-first setup with flexible hours as part of a distributed, global team
Generous paid time off (based on EOR employment)
Company laptop provided
A quick hiring process – 3, occasionally 4, interviews, with fast decisions afterwards
ABOUT THE COMPANY They’re an early-stage AI company building a proactive assistant aimed at the 5+ billion people currently stuck using non-AI-native tools for everyday things – email, notes, tasks. The focus is squarely on reliability: long-running workflows, persistent context, and tasks that actually get done, even though the underlying models aren’t fully deterministic.
